All similar devices with which I am familiar, provide for waxing thethread or yarn at the time it is woundupon spools, which spools are usedon the knitting machines. My device however permits. winding of thethread or yarn'upon the spools inan unwaxed condition and provides forwaxing upon the knitting machine, the benefits fromthis being numerous.Less wax is necessary by theuse of the invention,'tlie knitting machineneed not be stopped from time to time on account; of the thread oryarn being wound upon the spools: in a 'dry' condition, such conditionpreventing the yarn or thread from'sticking upon the spools, whichstick-' ing now causes jerking of certain springs of the machine andresultsin automatic stopping of such machine,'just as if the thread oryarn had become broken. Y

The mjachinei'when provided with my ole-- vice; will be kept clean ofwaxdirt, which is' particularly advantageous. in regard to "theaforesaid springs; as'when theyh-ecome' gummed with wax or the like;they will not properly act to automatically stop the maw causingloopholesin'the material, commonly knownas drop stitch, I

My inventionprovides for uniform; waxing'of the thread or yarn, whereas prev ously,the thread orthelike'was' not uniformly-waxed, and wherever heavily.waxed would cause a" thickness inlthe completed material, and whereverlightly waxed, would cause a thin place.v w 7 T One operator may attendto twice 11865 many machines when they are equippedwith my invention andthe work will be of better v quality because said invention willeliminate frequenflbreaking of threads as they are drawn from heSPoolsI" These threads re- 7 I tain their uniform strength andtheirfreedom from each other, eliminating sticking of threads together. thesame when it is unwound from the spools Machines equipped with myinvention need not be repeatedly" adjusted and readjusted with" regardto hooks which support the'work, which operations must follow each timethe threads break. Very often, after each such 0' eration', some hooksare left loose and w en thus neglected, they will break after awhile,causing" more trouble, material non-uniform, losing time, etc.v I

It is one object-of'the invention to provide a new and improved waxingdevice from which all; of the advantages hereinbefore enumerated will"flow. Another object of the presentinvention is to generally'sim-pli fythe construction and so'form a waxing device" that it may'beread- Myassembled and disassembled and may he I easily adjusted and-repaired.chine in case of breakage "of the thread or" .Another aim is to provideclearance be tween the wax block and an upstanding sleeve on thetable,which" sleeve is received a in an opening in the block, said clearanceserving to collect any dirt, dye-stuff orthe like from the threadand'preventing it from. covering the lower surface of the block, whichwould prevent proper waxing of the thread. p 11.0 With the foregoing inView, the invention" resides in the novel suhj ect" matter; hereinwhichthet'able 10o 1 after desc:ibed and claimed, the description beingsupplemented by the accompanying drawing.

Big. 1 is detail perspective view oft-he waxing device supported upon anadjustably mounted arm; and

Fig. 2 is a vertical central sectional view through the waxing device.

in the drawings above briefly described, the numeral 4L designates abeam supported in any desired manner.- Upon one end of this beam, I haveshown an angularly adjustablesupport- 5 for a vertically swingingcarrying arm 6 of the waxlng device. By

reason of the vertical swinging of this arm,

desired tcnsioning of the thread being waxed, 1s effected. sirednumber'of the supports 5, arms 6 and avaxing devices and if desired, twoor more of said supports 5 may be mounted upon each beam 4t. Thus,either one or a battery of many of the tenslonmg devices may be arrangedon one beam 4, whileseveral beams formed with a central opening 9through which the post or spindle 7 passes, a nut 7 being threaded uponsaid post or spindle in contact with the bottom of-the cup, so as to notonly tightly secure said cup in place, but to rigidly anchor the post orspindle, and permit vertical adjustment of it.

Closing the open upper side of the cup 9 and forming a table to supportawax cake N, is a disc-like'plate or cap 10 having a depending, flaredskirt or flange 11, the latter being spaced outwardly from the annularexposed edge of the cup By the provision of this cup, the table closingits open upper side, and the flange 11, no lint, threads, dirt or thelike can reach the lower portion of the post or spindle 7 to interferewith proper action of the device, and the upper portion of said post orspindle is covered and thus protected, as will hereinafterap pear.

The table 10 is formed with a central opening 12, larger than the postor spindle 7, and the lowerend of a cylindrical tube or sleeve 13 istightly pressed into said opening and is thus rigidly attachedtothe'table 10. Pressed firmly into the lower end of tubeor sleeve 13and crowding it tightly outward against the wall of the opening '12, isa bushing 14 whose lower end is provided with an outstanding annularflange 15 lying tightly against the lower side of the table Th re may beany deweight of the rotatable parts of the device and the wax cake W issupported anti-fric- 'tionally upon the upper end of the post or spindle7, and the bushing l-i which surrounds said post or spindle, merelyholds the table against angling with respect to the adjacent, stationaryparts. Vlhen the table 10 is thus supported, there isfrom one totwo-thousandths of an inch clearance between it and the cup 9, whichclearance may be obtained by using the nuts 7 vertically adjust the postor spindle 7 to the required extent.

The Wax cake W, it will be observed, is of cylindrical form and isprovided with an axial bore 19 to receive the sleeve or tube 13, and thelower portion of this wax cake is counterbored at 20, providingclearance between it and said tube or sleeve, so that any lint, dirt,dye-stud or the like from the thread 21 may accumulate in this clearancespace instead of coating the lower side of the waxing operation.

Guiding means for the thread may well comprise an inverted L-shaped eyemember 22 having thread guiding eyes 23 and 24, spaced differentdistances from the vertical part or shank 25 of said member. This shankpasses through or into an opening 26 in the arm 6 and is held by a setscrew-27 When this screw is loosened, the entire member 22 may be raisedor lowered as occasion may demand, to properly guide the thread 21 on alevel with the table 10, and said member 22 may be swung laterally so asto guide the thread to the desired portion of the device. Thisadjustability is exceptionally desir-able when a table of one size. isremoved and another table substituted to carry either a larger or asmaller cakeof wax, as the case may be. c

While the operation of the device would probably be understood from theforegoing, it may be brieflyexplained as follows:

The thread is drawn between the wax cake W and the supporting table 10and by reason of the fact that the thread engages adjacent faces of thecake and the table at points spaced from the post or spindle 7 and thebearing sleeve, rotary motion will be imparted to the block and to thetable.

' The "waxing operation is facilitated by having the wax cake rotate andit will of course be understood that this cake is free to movedownwardly upon the post or sleeve 13, as

and 8 to "wax cake and interfering with the proper p it wears away. Theweightof the wax restng upon the thread as wellas the rotary I movementof the wax cake and table, are

v lowed. However, within the scope'of the invention as claimed,variations may be made.

I claim:

and sleeve and closing the end of the latter.

instrumental in effecting the desired waxing operation.

As excellent results are obtainable from the details disclosed, they arepreferably 01- 1. A thread Waxer comprising, a substan tially verticalpost, a cup surrounding the post near its lower end, a sleeve rotatableabout the upper portion of. thepost and adapted for passage through anopening in a wax cake, a thread supporting. cap closing the upper end ofthe cup, a bearing bushing arranged centrally'of the-cap and surroundingthe medial portion of the post, and an anti-friction bearing between theadjacent outer ends of the post and sleeve.

2. Athread waxer comprising, a substantially vertical post, a' cupsurrounding the post near its lower end, a thread supporting tableclosing the upper end of the cup and extending radially beyond the edgeof the latter, a depending skirt at the periphery of the table, abushing centrally disposed in the table and surrounding the medialportion of said post, a bearing sleeve secured around a portion of saidbushing and extending up wardly, beyond said post for passage through anopening in a wax block, and a bearing cap connecting the outer ends ofthe post 3. A thread waxer comprising'a'n upstand the post, a sleevesurrounding the post above- -sa1d table, and having a bearing resting onsaid post, the lower end of said sleeve being tightly pressed I intosaid opening, and a bushing tightly pressed into the lower end ofthesleeve to crowdthe latter outwardly against the wall of said opening,the lower end of said bushing being provided with; out.- standing meanslying tightly against the lowerside of the table, said bushing rotatablysurrounding said post.

4-. In a threadfwax'er, an upstanding post, a thread supporting tablehaving an upstanding bearing sleeve around and protecting the upperportion of said post, and dirt excluding means-adjacent to the. lowerend of the post, said means comprising an up wardly opening cup tightlysecured to and surrounding the post with its upperedge in close"proximity to the lower side of the table, and a depending annular skirton the edge of said table, surrounding said cup.

5. In a thread waxer, a rotatable table having an upstanding cylindricalmemberf at its center, and a cake of wax bored vertically I to receivesaid member, the lower portion of l i said wax cake being counterboredto form a dirt receivingchamberthereby keeping the waxing face of thecake clean.
